Complete Documentation of Appian Expression Language?

I have been unable to find a starting point to the COMPLETE documentation of the Appian expression language (I don't know the correct name as I have not been able to find one).

As an example, I found this by searching Google:

https://docs.appian.com/suite/help/23.3/expression-advanced-evaluation.html

But, this seems to be a random orphan page. I am unable to find a series of pages to which this belongs, and if I start from the menu on the upper left, I don't see how one would encounter this page by navigating that menu.

I have found the page with documentation to all the functions, but not a complete FULL documentation to the syntax of the expression language. I would absolutely love to read it in its entirety instead of having vague ideas of what can be done and how it works from random examples.

Where can I find this documentation that I seek? Am I overlooking something obvious?

Thank you

    Hi Ryan,
    First of all go through the appian developer course, which will help you to get to know about the basics of appian, and also the core concepts & objects of appian. Link - https://academy.appian.com/#/curricula/7dc6be23-7518-4285-bfc8-cdbf8d4a4b9d
    In this course, there are many small tasks that will help you to create a small dummy application. After that start your journey by creating a demo application of your choice. AFAIK, for the expression rule the whole game depends on the functions, so go through the Appian's functions and read their documentation for their right usage. 
    The documentation of Appian functions - docs.appian.com/.../Appian_Functions.html
    This site has use cases to use functions in expression rules in different conditions - docs.appian.com/.../Function_Recipes.html

    Thank you for taking the time to answer, but what you are presenting is exactly what I was attempting to explain that I do not want: seeing the expression language by examples only and not by complete front to back documentation.

      I see the problem now. I generally keep my zoom level high on all websites to have larger fonts. When I do that with the Appian site, the menu you have highlighted on the left disappears, so I was never seeing those options!
